摘要
为了对油井杆、管偏磨进行有效的治理,对近三年应用的多种防偏磨工具按照技术评价、使用效果、性价比以及质量保证的评价方法,从结构、材质、质量等方面优选出了双向耐磨接箍、叶片扶正器、玻璃内衬管等应用效果较好的防偏磨工具。在结合偏磨机理分析和治理对策的基础上,针对高液量和低液量斜井、稠油、高含蜡斜井等井况制定了相应的综合配套措施并进行了现场推广应用,实现了短周期井的有效治理,为今后井下工具实行优胜劣汰提供了一条有效的途径。
To prevent rod and pipe deviation and wearing effectively, multiple side wearing resistant tools used in the past three years are evaluated from the perspectives of technical evaluation, application effect, ratio of performance to price, and quality assurance. Some tools with excellent application effect are selected in terms of structure, material, and quality, including bi-directional wearing resistant coupling, vane centralizer, and vitric lined pipe. Based on the mechanism analysis and countermeasures of deviation and wearing, in view of the deviated wells with high and low liquid loading, viscous oil, and high vax content, corresponding systematic measures are applied to the field, fulfilling effective treatment of short-period wells and providing effective measures for selecting optimum down_hole tools in the future.
